“…Concentrations of 90Sr were found as high as 440 pCi/g in mulberry vegetation (Moms alba). Deep-rooted desert plants have also been known to translocate 90Sr to foliage (Klepper et al 1979). With the exception of 3H, no other radionuclides were accumulated to a significant degree above background levels in shoreline vegetation upstream or downstream of the 100-N Springs site.…”

“…Certain desert plants have roots that grow to depths approaching 10 m (33 ft) (Napier 1982); however, root penetration to these depths has not been demonstrated for plants in the 200 Areas. Rabbitbrush roots have been found at a depth of 2.4 m (8 ft) near the 200 Areas (Klepper et al 1979). Mosses and lichens appear abundantly on the soil surface; lichens commonly grow on the shrub stems.…”

This document describes the Hanford Site environment (Chapter 4.0) and contains data in Chapters 5.0 and 6.0 that will assist users in the preparation of National Environmental Policy Act-(NEPA-) related documents. Many NEPA compliance documents have been prepared and are being prepared by site contractors for the U.S. Department of Energy (DOE), and examination of these doc lrnents reveals inconsistencies in the data presented and the method of presentation. Thus, it seemed necessary to prepare a consistent description of the Hanford Site environment to be used in preparing Chapter 4.0 of environmental impact statements and other site-related NEPA documentation. The material in Chapter 5.0 is a guide to the models used, including critical assumptions incorporated in these models in previous Hanford NEPA documents. The user will have to select those models appropriate for the proposed action. Chapter 6.Q is essentially a definitive NEPA Chapter 6.0, which describes applicable federal and state laws and regulations. In this document, a complete description of the environment is presented in Chapter 4.0 without extensive tabular data. For these data, sources are provided. Most subjects are divided into a general description of the characteristics of the Hanford Site, followed by site-specific information where it is available on the 100, 200, 300, and other Areas. This division will allow a person requiring information to go immediately to those sections of particular interest. However, site-specific information on each of these separate areas is not always complete or available. In this case, the general Hanfotd Site description should be used. To enhance the usability of the document, a copy of the entire text is available on an IBM PC diskette in WordPerfect 5.1 on request to C. E. Cushing at (509) 376-9670. Macintosh diskettes are also available (Wordkrfect). The figures can be obtained by contacting the Boeing Company Services Richland (BCSR) Graphics Department, located in the Pacific Northwest Laboratory Sigma I Building and using the classification number in the lower right corner of each figure. Janelle Downs kindly provided Figure 4.3-1. Following are the personnel responsible for the various sections of this document and who should be contacted with questions:

The results reported here establish the relevance and propose a method for including biotic transport in the assess111ent and 1 icensing process for commercial low-level waste disposal sites. Earlier work identified the biotic transport mechanisms and process scenarios linking biotic transport with does to man, and developed models for assessment of impacts. !n this, the second phase of the project, we focused on a review of the sub-models of the B!OPORT computer code and scenarios that were developed in Fhase I. Also site specific assessments of the relevance of biotic transport were conducted for two commercial low-level waste disposal facilities. The resulting Case calculotions indicate that the current BIOPORT/f•1AXI1 models predict lower doses than the previous ordPr-of-magnitude estimates developed in Phase I. However, the resulting doses, depending on model and scenario assumptions, range from the same order-of-magnitude to an order-of-magnitude lower than the doses from the comparable intruder-agriculture scenaric. The efforts to review and enhance the BIOPORT model resulted in the following: • no change in the sub-model representing waste package form de campo~. it ion 4.4.1 Cover Cor1figuration 4.4.2 Erosion Rates. .. . 4.4.3 Plant Populations. . 4.4.4 Animal Populations o o 0 0 4o4o5 ~Jaste-Package Form Integrity \' 1 •i iii 1.1 1.1 2.1 2 .I 2.2 2.4 2.5 2.5 2.7
